Leech? June 9, 2010 Here is a leech (I think) that I see fairly frequently at my property in “cloud forest” at 2100m on the eastern slope of the Western Cordilla in Valle De Cauca. It´s about 9cm long. Can you identify it for me? Pitter Valle De Cauca, Colombia

Leech or PLanarian?

Dear Pitter, We are very excited to have received your letter, because it represents the first posting to our site for a Leech. We did some research, and Leeches are actually considered to be Worms, and according to the Australian Museum website, they belong to the same class as earthworms, Clitellata. You may also find information on Wikipedia. Alas, we do not have the necessary knowledge to further classify your particular Leech.
